Cysteine From Feather Meal And Sulfur Amino Acid Requirements For Growing Steers, Mark Klemesrud, Terry J. Klopfenstein
Cysteine From Feather Meal And Sulfur Amino Acid Requirements For Growing Steers, Mark Klemesrud, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Ninety individually fed steers were used to determine how cysteine from feather meal could replace dietary methionine in meeting their requirements for sulfur amino acids. Treatment proteins included blood meal, blood meal plus incremental levels of feather meal or blood meal plus incremental levels of rumen-protected methionine. Addition of sulfur amino acids to blood meal from feather meal or rumen-protected methionine improved average daily gain (P < .05). Rumen-protected methionine elicited a greater gain response than feather meal (P < .05). Feather meal can provide some of the sulfur amino acids lacking in blood meal. However, additional methionine may further improve performance.
Continuous Vs Rotational Stocking Of Warm-Season Grasses At Three Stocking Rates, Bruce Anderson, Mike Trammell, Terry J. Klopfenstein
Continuous Vs Rotational Stocking Of Warm-Season Grasses At Three Stocking Rates, Bruce Anderson, Mike Trammell, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Pastures containing big and little bluestem, indiangrass, sideoats gramu, and switchgrass were stocked with 2.1, 2.7, and 3.3 yearling steers/acre from June to August. Continuous stocking and six-paddock rotations were used. Grazing terminated early on most continuously stocked pastures due to low herbage mass. As stocking rate increased, ADG declined; continuous Stocking produced highest (1.6 lbs) and lowest(. 69 lbs) ADG. Gai1n/acre was unaffected by stocking rate using rotational stocking (224 lbs/acre) but declined,from 250 to 133 lbs/acre as stocking rate increased using continuous stocking. Continuous stocking caused big bluestem to replace little bluestem and indiangrass and caused a slight …

Effects Of Sire Epd, Dam Traits And Calf Traits On Calving Difficulty And Subsequent Reproduction Of Two-Year-Old Heifers, Dave Colburn, Gene H. Deutscher, Don C. Adams, Merlyn K. Nielsen, Pete Olson
Nebraska Beef Cattle Reports
A three-year study evaluated effects of sire birth weight EPD, heifer and calf traits on valuing difficulty and subsequent rebreeding of two-year-old cows. MARC II yearling heifers (n=550) were assigned for breeding to one of four angus sires with birth weight EPD of -2.1, -1.8, +6.3 and +5.9 lb. Of all heifer weights, only dam birth weight affected calving difficulty score. Heifers requiring caesareans had smallest pelvic areas. Calving difficulty increased as calf birth weight and external measurements increased. Low EPD sires produced calves with smaller head and foot circumferences and less dystocia. Degree of calving difficulty did not affect …

Effect Of Rumensin And Feed Intake Variation On Ruminal Ph, Rob Cooper, Terry J. Klopfenstein, Rick Stock, Cal Parrott, Dan Herold
Nebraska Beef Cattle Reports
Six ruminally-fistulated steers were used to evaluate the effect of Rumensin and feed intake variation on ruminal pH. Steers were adapted to a 92.5 percent concentrate diet and then subjected to three levels of intake variation: ad libitum, intake variation of 2 lb/day, and intake variation of 4 lb/day. Feed intakes and ruminal pH were monitored continuously throughout the entire trial. Results indicate that Rumensin reduced acidosis by elevating average ruminal pH and decreasing are of ruminal pH below 5.6. In addition, Rumensin stabilized rate of intake and daily ruminal pH fluctuation at the high level of intake variation.
